Syntheses of the empty metalla-prisms 6, 7, and 8 have been reported previously.14 Ellagic acid (5) encapsulated in metalla-prisms 9, 10, and 11 were readily prepared quantitatively by the reaction of one of the binuclear [Ru2(p-iPrC6H4Me)2(dobq)(MeOH)2][CF3SO3]21,40 [Ru2(p-iPrC6H4Me)2(donq)(H2O)2][CF3SO3]22,41 or [Ru2(p-iPrC6H4Me)2(dotq)][CF3SO3]2314 acceptors with the tripyridyl donor 442 and ellagic acid (5) in a 3:2:1 ratio (Figure 1). The addition of diethyl ether to the concentrated reaction mixtures resulted in the isolation of analytically pure hexanuclear cages as crystalline solids. All the cages were fully characterized by 1H NMR, electrospray ionization mass spectrometry, and UV/Vis absorption.
